| Abstract: |
| As a new tool of information resource integration, topic map is very promising in the field of integrating digital resources. To some extent, the relevance between topics and resources reflects the relatedness between resources and users inquires. This paper proposes a kind of relatedness algorithm, which analyzes the resources from the own contents and users dynastic behaviors. By some related tests, it indicates that this algorithm is relatively stable and can make the resources in good order. 5 figs. 2 tabs. 11 refs. |
| 中文摘要: |
| 主题图作为一种新型的信息资源整合工具，在数字资源整合领域有着广泛的应用前景。主题图中资源与主题间的相关度在一定程度上反映了资源与用户查询需求间的相关程度。基于此，本文提出了一种主题文本资源间相关度算法，主要从资源本身及用户动态使用行为两方面深入分析。相关算例试验结果表明，该算法相对稳定，整体上对文本资源排序的效果较好。图5。表2。参考文献11。 |
